Abstract

The increasing cone angle of current high-end and future CT systems leads to a decrease in image quality if approximate cone-beam reconstruction methods are used. According to an exemplary embodiment of the present invention, an iterative four-dimensional cardiac CT reconstruction is provided, in which phase volumes are selected from the four-dimensional data set, each having the same spatial volume at different phase points. Corresponding voxels inside these phase volumes are then forward projected onto the same projection. After calculation of a different projection, these voxels are updated. This may provide for an efficient implementation of an iterative four-dimensional cardiac cone-beam CT reconstruction.
